San Jose police have contacted the couple’s juvenile son and are attempting to locate their second adult son for questioning. Detectives don’t consider the Rabbis’ adult son a suspect at this time, according to KTVU-TV.

The Rabbis were long-time residents of the neighborhood and were active members in the Islamic community. Their deaths have shocked the community.

“I’ve known him for 30 plus years, so it’s a loss,” Hasan Rahim, of the Evergreen Islamic Center, told KTVU-TV. Rahim said they were dedicated members of the mosque and were natives of Bangladesh.

“He always asked me about my family, now I can’t answer him back,” Faisal Yazadi, who also attends the Islamic Center, told the station.

San Jose police told the San Jose Mercury News the “incident was not a random act of violence and the suspect was someone familiar to the family.” A suspect or motive has not been identified as of Tuesday.

The Evergreen Islamic Center said they’re opening their doors to offer support for anyone in need as a result of the murders.

Anyone with details of the couple’s death is urged to call San Jose police Homicide Sgt. Pat Guire or Det. Ken Tran at 408-277-5283. Anonymous callers can contact the Crime Stoppers Tip Line at 408-947-7867.
